NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 564,895, dated July 28,1896.

Application filed February 5 1896. Serial No. 578,109. (No model.)

To @ZZ whom, t may concern,.-

Be it known that I, DIRK LANDSTRA, a citizen of the United States, and a resident of Hackensack, county of Bergen, and State of New Jersey, have invented a new and useful Improvement in Bottles which Cannot be Filled a Second Time, of which the following is a specification.

My invention relates to an improvement in bottles which, when once filled, cannot be filled a second time without mutilating the same or its attachments; and the objects of my improvements are to provide a protector to be inserted within the neck of the bottle; further, to provide means by which the protector may be securely held therein, and cannot be removed therefrom without breaking the bottle. l attain these objects by the construction illustrated in the accompanying drawings, in which- Figure l is a longitudinal vertical section through the cork, neck, and part of the body of the bottle and through the protector. Fig. 2 is a similar section as that shown in Fig. l with the cork removed from the mouth of the bottle and the valves opened. Fig. 3 is an elevation of the protector removed from the bottle. Fig. t is a plan view of the protector, showing the upper valve thereof; and Fig. 5 is a plan view illustrating the lower valve of the protector.

Similar letters and figures refer to like parts throughout the several views.

A represents the neck, B the body of the bottle, and D the right -Yangled shoulders' formed at the junction of the neck and the body of the bottle, on the inside thereof.

E represents the protector shown in Fig. l in its proper position within the neck of the bottle.

4.- 4 refer to the upper and lower valve-covers, and 3 3 the upper and lower valve-openings of the protector.

2 2 represent the pintles of the hinges of the valve-covers, and m fm are spring-hooks formed integral with and made a part of the protector, adapted to be sprung under the right-angled shoulders D D on the inside of' the bottle when the protector .is inserted within the lower portion of the neck of the bottle.

5 5, in Fig. 3 of the drawings, refer to rubber bands drawn tightly around the upper and lower edges of the protector, which prevent the air from entering between the neck of the bottle and the protector proper, and vapors and gases contained or held within the contents of the ,bottle from escaping into the atmosphere.

The name of the manufacturer and the 6o trade-mark by which the goods sold in they bottles are protected may be stamped or otherwise .placed upon the body of the protector, between the two rubber bands, and thereby easily read through the neck of the bottle.

The name of the manufacturer and the trade-mark under which the contents of the m bottles are sold may also be placed upon the upper and lower valve-covers 4 4.

The top valve-cover of the protector is of 7o the same form as the lower one, but the top cover is larger and the free end thereof eX- tends farther over, nearer to the inner surface of the neck of the bottle, than the free end of the lower cover, and the opening of the 7 5 upper valve is larger than the openin g of the lower valve. Furthermore, of these valveopenings one is larger than the other, and of their respective covers the upper one is larger than the lower one, and an instrument 8o introduced through the opening of the upper valve, when pushed downward, would strike the top of the lower valve-cover, and'close the same upon its opening.

The contents of the bottle can easily be poured out by raising the upper valve, inverting the bottle, and then the pressure of the contents within the bottle will readily open the lower valve-cover, and the contents will ow out. 9o

The upper valve-cover may easily be raised by inserting within the neck of the bottle a long pointed instrument, but this instrument cannot be passed downward through the lower valve-opening on account of the long free-ended projection of the upper valvecover, because the two valve-openings do not register one with the other, and, furthermore, because the valve-cover nearer the open end of the bottle is only, and can be but partially roo opened.

The device is simple in its construction,

and its mode of operation is manifest and obvious. A detailed description of its operations is thereforeunnecessary.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-

l. In bottles that cannot be filled a second time, the combination with the protector, E, having upper and lower valve-openings 3, 3, the said openings provided with valve-covers, 4, 4, limited in their upward movement, the upper cover larger than the lower cover, and the bottle having right-angled shoulders, at the junction of the body and neck thereof, means on the protector to engage said shoulders,y substantially as herein shown and described.

2. In bottlesy that cannot be refilled, the combination of the bottle having right-angled shoulders D, D, at the junction of the body and neck thereof, the protector E, having springehooks m, m, with right-angled shoulders, adapted to be sprung under the said right-angled shoulders ofthe bottle, the said protector E, provided with upper and lower valve-openings 3, 3, the upper one larger than the lower opening, and having valvecovers 4, 4, limited in their movement, the upper co-ver larger than the lower cover, and the rubber bandsz0rgaskets,tightly drawn around the upper and lower edges of thesaid protector, whereby gases arising from the. contents of the bottle cannot escape, substantially as herein shown and described.

3. In bottles that cannot be lled a second time, the combination of the bottle provided with right-angled shoulders at the junction of the body and neck thereof, the protector having downwardly-projecting spring-arms, with right angled shoulders on the ends thereof, adapted to be firmly held under the fright-angled shoulders of the bottle, at the junction of the-neck and body thereof, the
